How a Tire Pressure Monitoring System Works

As its name suggests, a tire pressure monitoring system is more than a single part. In fact, TPMS involves a valve and a sensor, and it's also important to know that not all TPMS systems are created equal.There are two kinds of TPMS technology–indirect and direct. Indirect TPMS approximates tire pressure indirectly by using data from the vehicle's antilock brake system (ABS). Direct TPMS provides a more accurate calculation of your tire pressure using data gathered directly from a sensor placed inside each tire.

In either case, if a tire is detected to be underinflated by 25% or more, an alert lights up on your dashboard. But with direct TPMS, drivers are alerted sooner and–if the car is equipped with the four-tire TPMS display–can even see readings for each tire. One of the largest downsides of an indirect TPMS system is that it cannot detect when all four tires are low in pressure, which can happen quite frequently if tire pressure is not checked on a regular basis.

RFQ:

A: What exactly does it mean when my TPMS warning light comes on?

B: If the TPMS warning light comes ON and flashes ON for one second and OFF for three seconds, this indicates a malfunction with the vehicle's TPMS system.

If the TPMS warning light comes ON and stays ON, take caution. This means that one or more of your tires may have a low-pressure condition. You should carefully slow the vehicle and park in a safe and secure place. You should then inspect all of your tires and check the air pressure. The correct air pressure for your vehicle can be found on the placard, usually located on the inside door panel.

A: Why does tire pressure change?

B: Many factors affect tire pressure including ambient temperature changes and tire damage such as punctures. Tire pressure drops about 1 psi for every 10°F drop in ambient temperature. Additionally, tires can lose as much as 1.5 psi per month as air escapes the tire and rim naturally.

A: What do I do when my TPMS light comes on during cold weather?

B: Does this really mean my tires are low? Any time that the TPMS warning light comes ON, there is a possible low tire pressure condition. Tire pressure can drop due to cold conditions, and this drop in pressure may cause the TPMS light to come ON. As the tire warms up under normal driving conditions, the light may turn OFF. If the cold weather conditions cause the TPMS light to stay ON, check the tire pressure (when tires are cold) and inflate the tire to the proper pressure indicated on the door placard.
